Invisible but everywhere

Our products are often invisible when the building is ready, but they are an essential part of the building process.

Buildings are one of the largest energy consumers. They account for over 40% of global energy use and 33% of global CO2 emissions.

Our products actively help to fight climate change by improving a building’s energy efficiency and its CO2 emissions.

How do we improve energy efficiency?

1
By thermally insulating structures
  • Our PU foams seal gaps, cracks and thermally insulate joints, thus preventing energy losses in buildings and reducing their CO2 emissions.
  • Penosil PU foams save over 70 times more energy during their lifecycle than was needed for their manufacturing process.
  • 1kg of PU foam saves 1,000kg of CO2 during its lifecycle. By comparison, a tree can absorb around 1,000kg of CO2 over its 100year lifetime.
  • PU foam is an excellent insulation material as it can access otherwise hardtoreach places, and it has a lower thermal conductivity than mineral wool.
  • Correctly applied PU foam also acts as sound insulation and reduces the risk of condensation and mould.

By improving structures’ airtightness
  • Buildings’ airtightness helps to prevent air leakages, humidity problems and condensation, increases fire safety and minimises noise problems.
  • The air leakages account for about 25% to 40% of heat losses in a cold climate and 10% to 15% of heat gain in a hot climate.
  • Even the smallest unsealed crack in the structure can have a big impact on a building’s energy efficiency.
    For example, a 1mm-wide unsealed joint in an exterior wall in wintertime can increase the wall’s heat loss by around 4.8 times more than a sealed joint.
  • To improve a building’s airtightness, it is crucial to use sealants to seal even the smallest crack in the structure.

The typical places for air leaks are:

Doors 10%

Windows 15%

Roof construction 25%

Penetrations through building’s envelope 15%

Building’s envelope 35%
